Abstract: The present invention relates to an improved PTAT current source and a respective method for generating a PTAT current. Opportune collector currents are generated and forced in two transistors exploiting the logarithmic relation between the base-emitter voltage and the collector current of a transistor. A resistor senses a voltage difference between the base-emitter voltages of the two transistors, which can have either the same or different areas. A fraction of the current flowing through the resistor is forced into a transistor collector and mirrored by an output transistor for providing an output current. By this principle an all npn-transistor PTAT current source can be provided that does not need pup transistors as in conventional PTAT current sources. The invention is generally applicable to a variety of different types of integrated circuits needing a PTAT current reference, especially in modern advanced technologies as InP and GaAs where p-type devices are not available. For example, the PTAT current source circuit of the invention can be used in radio frequency power amplifiers, in radio frequency tag circuits, in a satellite microwave front-end.

Abstract: The invention relates to a magnetic sensor device (100) with a primary and secondary detection unit (P, S), each of which comprises a magnetic sensor element and a magnetic field generator. In a preferred embodiment, the magnetic sensor elements are GMR elements (12, 22) with the same sensitive directions (D 12 , D 22 ), and the magnetic field generators are parallel wires (11, 21) which are supplied by an evaluation and control unit (40) with anti-parallel magnetic excitation currents. The magnetic excitation currents generate magnetic excitation fields (Bn, B2i) with opposite sense of rotation which in turn induce oppositely directed magnetic reaction fields (B' 11 , B' 21 ) in magnetized particles (1) provided in an investigation region (2). The magnetic reaction fields (B' 11 , B' 21 ) therefore have opposite effects on the GMR elements, yielding an increase in the difference (Δ) between the output signals of these elements. In a preferred embodiment, four detection units are arranged in a Wheatstone bridge.

Abstract: A current-mode controlled DC/DC converter receives an input voltage (Vb) and supplies an output voltage (Vo). A controllable switch (S1) is coupled to an inductor (L) to obtain a periodically varying inductor current (IL) through the inductor (L). A current-mode controller (1) compares (10) the output voltage (Vo) with a reference voltage (Ver) to Obtain an error signal (ER), and applies (11) a transfer function on the error signal (ER) to obtain a control signal (CO; CIO). A correction circuit (7) adds to the control signal (CO; ICO) a correction signal (ICR) representative for a difference between an original value of the control signal (CO; ICO) and an average value of the inductor current (IL) to obtain a modified control signal (MCO; IMC).
